Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper proposes a feasible scheme for quantum spin-state teleportation and tests of EPR correlations using 151 MeV entangled protons produced via exclusive proton-deuteron breakup, demonstrating that the polarization of a target proton can be transferred to a distant entangled partner and that scattering one member of a Bell-state pair induces identical polarization in the other.
This study extends the FastReso framework to incorporate thermal broadening of light vector-meson spectral functions, revealing that while finite-width effects increase low-momentum pion yields and partially reduce discrepancies between models and LHC data, they do not fully resolve the soft pion puzzle in heavy-ion collisions.
This paper presents next-to-next-to-next-to-leading logarithmic (NLL) resummation combined with fixed-order corrections to predict lepton-jet azimuthal angular distributions in deep-inelastic scattering, offering a precision framework for probing the nucleon's three-dimensional structure and analyzing data from HERA and future electron-ion collider experiments.
This study demonstrates that optimizing a six-parameter Woods-Saxon mean field within a correlated-basis framework is essential for accurately reproducing nuclear charge radii and generating the high-momentum strength observed in elastic form factors, as failing to refit parameters when introducing explicit short-range correlations leads to significant errors.
This paper develops an effective field theory framework to describe the interaction between heavy quarks and a strongly coupled, non-dissipative quark-gluon plasma treated as a relativistic fluid, enabling the systematic calculation of heavy quark quasiparticle widths and scattering processes with fluid phonons.
This paper presents a reduced basis emulator for continuum-discretized coupled-channels calculations that utilizes proper orthogonal decomposition and Galerkin projection to achieve approximately 100-fold speedups with sub-percent accuracy, thereby enabling efficient uncertainty quantification and Bayesian parameter estimation for nuclear reaction studies.
This paper demonstrates that neglecting off-diagonal imaginary couplings in weakly bound nuclear reactions leads to a biased physical picture by overestimating total absorption and underestimating breakup contributions, thereby establishing the necessity of full-coupling CDCC calculations with coherent interference terms for accurate mechanism-resolved cross-section extraction.
This review reorganizes ten frontier questions in nuclear science and technology to provide an integrative research framework that connects fundamental physics, advanced methodologies, and strategic applications, offering a scholarly roadmap for the field's future development.
This paper applies first-principles many-body ab initio nuclear modeling with chiral effective field theory to calculate light dark matter mediator production rates at electron fixed-target experiments, revealing that a quasi-elastic treatment can increase predicted signal yields by up to two orders of magnitude compared to standard phenomenological parameterizations.
This paper demonstrates that fluctuation-response relations in a rotating stochastic Landau model emerge from an inherent symmetry of the coarse-grained Martin-Siggia-Rose path integral, which links entropy production to time-reversed dynamics and yields Ward identities that align with high-temperature fluctuation-dissipation relations only upon imposing the Einstein relation.
